1 Claim. 1 This invention relates to animproved; electric lighting or other service fixtureof, the general type wherein. the fixture housing is recessedv in the ceiling or other wall of a building or other structure.

It has been common practice to connect fixtures through terminal or outlet boxe of a con-. duit system which provide access for splicing and ductors of an electrical circuit from inside or outside of a fixture. Splicing and; adjusting electrical conductors from inside of the fixture, also cleaning, adjusting, repairing and servicing the fixture usually requires an electrician or other workman to stand ona ladder and, reach overhead, which is awkward and frequently hazardous, and it is the primary object of my improvement'to reduce these and other objections to aminimum.

A further object of my invention is to provide a lighting or other electric fixture which is designed so that it may be recessed within a structure and after installation may be readily removed through the face of said structure without interrupting electrical connections of the fixture.

Another object of my invention is to provide an electric fixture which permits the fixture to be readily removed from its recess and replaced in the structure in which it is employed without disconnecting the electrical conductors leading from the accompanying splice or other service box.

Another object is to provide an electric fixture installation of the aforesaid type which requires no extra pull box and for which no asbestos or slow burning supply wire is required under the Rules of Underwriters, or the National Electrical Code.

Various other objects and advantages of my improvements than those hereinafter specifically mentioned are contemplated and it is to be understood that the specific forms hereinafter described are merely illustrative and hence the detailed description thereof is not to be taken as limiting my invention.

In the accompanying drawings forming part view in. persp ct veo mv' m r ve h i xw tureinstallation showing portions of the wall structure and of the recessed fixture.

My improved fixture is applicable to a wall structure. such a A, of any desired type, that shown in the drawings beinga typical ceiling or; side wall. The wall structure shown has usual joists l0, and may or may not have cross supports ll, (Fig. 2), which assist in framing an opening I2; through the sectional button-board and Wall-board surface. or plaster finish l3. Said opening is of suitable shape and size to receive and recess. the. box-like housing F ofmy im- ,v proved electric lighting fixture through said opening and in said structure. A suitable fix-v ture supporting frame 13, comprising a surface plate l4 and a sleeve or collar l5 are provided, said sleeve being placed in the opening l2 through the surfacing l3 and acting as a plaster ground. The supporting frame B is. secured in desired position on the lower edges of the joist members Ill of the wall structure A, by its supporting plate l4 and nails orother suitable fasteners which are secured through said plate into the joists. The sleeve I 5 is of suitable width to line and protect the side of the recess opening through the wall structure and to provide a slip joint for receiving and holding the fixture housing F.

The plate ll of the supporting frame is extended on one side of the plaster ground and spaced outwardly away from the opening I 2 as shown in Fig. l to permanently support in fixed position away from the housing F a splice or other typical electrical junction box C in which the usual electrical current supply connections are adapted to be made and held. Detachable covers l9 and 20 on the front and back sides of the splice box provide access into the box for making splice connections.

The fixture housing F as shown also has a typical service box D which is mounted on one of the housing walls and is closed inwardly by a cover plate 2| Plate 2| is removable from within the housing, being held by screws 22.

The service box D is shown connected with the splice box C by a flexible extension conduit E, which contains electrical conductors such as 23. These conductors extend from the splice box through the service box to the lamp 24 or other service appliance contained in the fixture housing. The lamp as shown is supported by the socket 25, which in turn is mounted on the removable cover plate 2| so that connections can be made in the service box from within the housing.

The housing F of the fixture is removably secured in the supporting frame B by screws 26 which are applied from within the housing after the latter has been slipped through frame B into the recess in the wall structure. When thus secured the outer edge portion of the collar i extends through the wall finish I3 as shown in Fig. 1. While the housing is thus supported in the wall structure a cover 2'! having a light transmitting plate 28 forming a window can be removably secured over the open end of the fixture body and the contiguous marginal edge or opening l2 through the wall surfacing 13 by screws 29. By removing said screws 29 the cover 21 can be removed and after removal of screws 23 the housing F can be disconnected and slid outwardly through the supporting frame B. The conduit E is of sufficient length to permit the removal of the fixture housing through the supporting frame Without disconnecting any of the electrical connections as shown in Fig. 2. While the fixture housing is thus removed the inner cover I9 of thesplice box C is readily accessible through the opening in the supporting frame B and can be removed or attached. In this manner connections of the electrical service conductors in the splice box 0 can be serviced and connected or disconnected by reaching through the fixture and without interrupting the electrical current after connections have been made. After removal the fixture body can be readily replaced in the supporting frame, all of which assists the attendant in installing and servicing the fixture.

The fixture which I have shown and described and to which my improvements are applied need not have a service box D, it being contemplated that the flexible electrical service conductors leading from the splice or other service junction may be connected directly with the electrical appliance in the fixture body without the use of outlet box I). It is also contemplated that the fixture body F may be of any suitable design or of such character that it or its equivalent can be used for any useful purpose without departing from the principles of my improvement and within the scope or" the following claim. Various other modifications are contemplated within the spirit of the invention.

I claim:

A wall structure having a recess therein, a plaster ground for said recess consisting of a plate afixed to joist members of the wall structure and having an opening-defining integral collar with a portion thereof extending up into said recess and a portion extending down from the recess, a fixture housing inserted into the recess through said opening and removably connected to that portion of the collar extending up into the recess, an electrical terminal inlet at the top of the housing, a light-transmitting cover for the housing, means for attaching said cover to said housing, an electrical service junction box mounted on said plate immediately adjacent the recess and having a removable cover facing the recess, and a flexible slack electrical extension conduit connected between said inlet and the service box, whereby the service box is made accessible through the plaster ground when the housing is removed without interrupting electrical connection through said conduit.
